Beta Adrenergic Receptors: Skeletal Muscle

Posted on October 25, 2024 by Robert Barrington

One of the effects of administering β-adrenergic agonists to sheep, cattle and pigs is the increase in lean mass that they experience. Therefore β-adrenergic agonists are thought to stimulate hypertrophy, reduce protein degradation, or a combination of both. The mechanisms … Continue reading →

Cyclic AMP and Growth

Posted on October 23, 2024 by Robert Barrington

Evidence suggests that compounds such as caffeine, ephedrine and clenbuterol may be able to alter mammalian growth rates because they can alter intracellular levels of cyclic AMP (cAMP). This research has perhaps been exemplified by studies on cattle fed high … Continue reading →

Beta Adrenergic Receptors and Growth

Posted on October 22, 2024 by Robert Barrington

β-adrenergic receptors are those that bind adrenaline or noradrenaline, and which from this binding elicit a cellular response using the G-protein coupled cyclic AMP and protein kinase A system. This system forms the CREB (cAMP response element binding protein) system. … Continue reading →

Brown Versus White Fat

Posted on October 11, 2015 by Robert Barrington

There are two main types of adipose tissue in human physiology. These are designated white and brown adipose tissue (BAT). Discussion of their different physiological roles is important in any exploration of weight gain and fat loss. White adipose tissue … Continue reading →

L-Phenylalanine and DL-Phenylalanine: Differences

Posted on June 20, 2015 by Robert Barrington

L-phenylalanine is an essential amino acid required for the synthesis of proteins. In addition, L-phenylalanine is the substrate for the formation of the catecholamine neurotransmitters and hormones. The catecholamines are adrenaline, noradrenaline and dopamine, and in the brain they play … Continue reading →
