Genes involved in thiol release from cysteine and glutathione conjugates by Saccharomyces cerevisiae during wine fermentation
… influenced by three volatile thiols: 4MMP, 3MH and 3MHA. Considerable effort has been made during the last decade in order to understand how these desirable thiols are released by Saccharomyces cerevisiae during wine fermentation. So far, three types of thiol precursors have been found in …

The Effect of Pre-fermentation Fining & Other Post-harvest Manipulations on Sauvignon blanc Aroma
… in the varietal thiols 3-mercaptohexanol (3MH) and 3-mercaptohexyl acetate (3MHA). Surprisingly, a significant (p < 0.05) increase in ethyl (dihydro)cinnamate as well as benzyl alcohol as a result of G fining was also noted. Sensory analysis showed a Green veg aroma to help distinguish …

Identification of yeast genes involved in sauvignon blanc aroma development
… 2008. Two volatile thiols, 3-mercaptohexan-1-ol (3MH) and 3-mercaptohexyl-acetate (3MHA), reminiscent of grapefruit and passion fruit respectively, are critical for the main varietal characters in New Zealand SB. These aromatic thiols are not present in the grape juice, but are synthesized and …

Drivers of Sauvignon blanc aroma at harvest: C6 compounds, antioxidants, and sulfur
… immense potential to form 3-mercaptohexanol (3MH) via the addition of H2S to C6 compounds. However, both pathways have limitations to their relevance in oenological conditions and were not able to fully explain the high varietal thiol content in Sauvignon blanc wine. The practices undertaken …

Investigation of New Zealand Sauvignon Blanc Wine Using Trained Sensory Panels
… methoxypyrazine [MIBP], 3-mercaptohexanol [3MH], 3-mercaptohexanol acetate [3MHA], and ethyl decanoate). Each of these four aroma compounds were assessed in combination with three non-volatile polyphenolic compounds commonly found in Sauvignon blanc wine: catechin, caffeic acid and …

Effect of Carbohydrate-Protein Beverage on Glycogen Resynthesis and Muscle Damage Induced By Eccentric Resistance Exercise
… protein breakdown by urinary 3-methylhistidine (3MH), muscle soreness, isokinetic muscle strength, muscle glycogen resynthesis, and serum hormones. Untrained males (N=26) underwent a 9-day controlled meat-free diet and 24 hr urine collections. To reduce glycogen, subjects cycled for 40 min at 70% …

The Relationship Between Exercise-Induced Delayed Muscle Soreness and The Excretion of Urine Metabolites and Creatinine, 3-Methylhistidine and Hydroxyproline
… of creatinine (CRE), 3-methylhistidine (3MH), and hydroxyproline (OHP) were investigated as indices of muscle damage associated with exercise-induced delayed muscle soreness (DMS). Subjects (n = 28) maintained meat-free diets for six days. Twenty-four hour urine volumes were obtained from …

Effect of low temperature on Sauvignon blanc fermentation by Saccharomyces cerevisiae
… of the volatile thiol 3-mercaptohexan-1-ol (3MH) and higher alcohol concentrations, in agreement with the literature. The temperature effect on 3- mercaptohexyl acetate (3MHA), esters and fatty acids is largely modified by juice and strain, and these variables interact with one another in a …

Investigation into the partitioning of Lindane between air and dust in indoor environments
… 4.2 x 10-4mh-1, 7.67 x 10-5mh-1, and 3.03 x 10-3mh-1 respectively. The desorption constants Kd were 0.125h-1, 0.047h-1, 0.288h-1. The partition coefficients Kp were 4.8 x 101µgm-2, 4.08 x 101µgm-2, 1.05 x 102µgm-2, for the <20µm, >45µm<63µm, and whole dust respectively. The higher Kp value for …

The Effect of Post Exercise Nutrition on Anabolic Response to Resistance Exercise
Purpose: To determine the effect of four postexercise beverages, differing in macronutrient content, on metabolic response to an acute resistance exercise bout. Methods: Forty male subjects performed five sets of eight repetitions at 80% 1RM for leg press and leg extension, and then consumed one of …
