Steroid hormones secretion

Adrenocortical hormone (Section 27.6) A steroid hormone secreted by the adrenal glands. There are two types of adrenocortical hormones mineralocorticoids and glucocorticoids.

The tenn corticosteroids refers to steroid hormones secreted by the adrenal cortex. Corticosteroids are involved in a wide range of physiologic systems such as stress response, immune response, and regulation of inflammation, carbohydrate metabolism, protein catabolism, blood electrolyte levels, and behavior. 

Aldastenme is a steroid hormone secreted by the zona glomerulosa of the adrenal gland (Figure 10.5). The steroid hormones are biosynthesized from cholesterol. Aldosterone is called a mineralocorlicoid because it regulates the transport of minerals, Na and K- Aldosterone received its name because it contains an aldehyde group —CH=0. 

Corlan hydrocortisone, corticoliberin corticotrophin-releasing factor, corticorelin corticotrophin-releasing factor. CORTICOSTEROIDS as a family are natural steroid hormones secreted by the adrenal cortex, or are synthetic substances that closely resemble them. There are two main types GLUCOCORTICOIDS (corticosterone. cortisone and hydrocortisone) are essential for utilization of carbohydrate, fat and protein in the body, and in the normal response to stress. Naturally occurring and synthetic glucocorticoids have a powerful antiinflammatory effect. 

Phospholipids and glycosphingolipids are amphipathic lipid constituents of membranes (Chapter 10). They play an essential role in the synthesis of plasma lipoproteins (Chapter 20) and eicosanoids (Chapter 18). They function in transduction of messages from cell surface receptors to second messengers that control cellular processes (Chapter 30) and as surfactants. Cholesterol is mainly of animal origin and is an essential constituent of biomembranes (Chapter 10). In plasma, cholesterol is associated with lipoproteins (Chapter 20). Cholesterol is a precursor of bile acids formed in the liver of steroid hormones secreted by adrenals, gonads, and placenta and 7-dehydrocholesterol of vitamin D formed in the skin. In tissues, cholesterol exists primarily in the unesterified form (e.g., brain and erythrocytes), although appreciable quantities are esterified with fatty acids in liver, skin, adrenal cortex, and plasma lipoproteins.
