Aldosterone is the main mineralocorticoid steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland. [ 4 ] [ 5 ] It is essential for sodium conservation in the kidney, salivary glands, sweat glands, and colon. [ 6 ]
The outermost layer, the zona glomerulosa is the main site for the production of aldosterone, a mineralocorticoid. The synthesis and secretion of aldosterone are mainly regulated by the renin–angiotensin–aldosterone system. The zona glomerulosa cells express a specific enzyme aldosterone synthase (also known as CYP11B2).
This layer is the main site for production of aldosterone, a mineralocorticoid, by the action of the enzyme aldosterone synthase. [16] [17] Aldosterone plays an important role in the long-term regulation of blood pressure. [18]
Digestion is the first step to lipid metabolism, and it is the process of breaking the triglycerides down into smaller monoglyceride units with the help of lipase enzymes. Digestion of fats begin in the mouth through chemical digestion by lingual lipase. Ingested cholesterol is not broken down by the lipases and stays intact until it enters the ...
The following is a list of hormones found in Homo sapiens.Spelling is not uniform for many hormones. For example, current North American and international usage uses [citation needed] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling gonadotrophin.
The first identified mechanisms of steroid hormone action were the genomic effects. [12] In this pathway, the free hormones first pass through the cell membrane because they are fat soluble. [ 7 ] In the cytoplasm, the steroid may or may not undergo an enzyme -mediated alteration such as reduction, hydroxylation, or aromatization.
Cholesterol is the principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. [3] [4]Cholesterol is biosynthesized by all animal cells [citation needed] and is an essential structural and signaling component of animal cell membranes.
Aldosterone synthase is a protein which is only expressed in the zona glomerulosa [5] of the adrenal cortex and is primarily regulated by the renin–angiotensin system. [6] It is the sole enzyme capable of synthesizing aldosterone in humans and plays an important role in electrolyte balance and blood pressure. [7]
